Towards the Visible Light-Driven Water Splitting Device: Ruthenium Water Oxidation Catalysts with Carboxylate-Containing Ligands

, 2014
The presence of oxo and carboxylate ligands is crucial to decreasing the redox potentials of the oxygen evolving complex (OEC). It has been proved that negatively charged ligands can stabilize the high oxidation states of various transition metal-based ...

Metal–Ligand Cooperative Control of Reactivity in a Porphyrin Manganese(IV)–Oxo–Phenoxyl Radical Complex for Water Activation

ChemistryEurope
The Oxygen Evolving Complex (OEC) is a Mn4Ca cluster at the heart of Photosystem II that catalyzes the water oxidation reaction. Recent studies suggest the formation of a Mn(IV)‐oxyl species in the OEC, accompanied by a nonbonded tyrosinyl radical in the

Computational Characterization of Single-Electron Transfer Steps in Water Oxidation

Inorganics, 2019
The presence of single-electron transfer (SET) steps in water oxidation processes catalyzed by first-row transition metal complexes has been recently recognized, but the computational characterization of this type of process is not trivial.

An Overview of Significant Achievements in Ruthenium-Based Molecular Water Oxidation Catalysis

Molecules, 2019
Fossil fuels (coal, oil, natural gas) are becoming increasingly disfavored as long-term energy options due to concerns of scarcity and environmental consequences (e.g., release of anthropogenic CO2). Hydrogen gas, on the other hand, has gained popularity
